Application filed April 9,1913. Serial No. 759,999.

g C. Crimson- NIER, residing at St. Louis, Missouri, and being a citizen of the United States, have invented certain new and useful Improvements in Door-Operating Mechanism, .of which the following is a full, clear, and

exact description, such as will enable oth-- ers skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings,

which illustrate the preferred form of theinvention, though it is to be understood that the invention is not limited to the exact details of construction shown and de-.

end of the shaft, shown at the left of Fig.

1, by a bracket or gusset plate secured to one of the cross-bearers. In. addition, Fig. 1 shows fragmentary portions'of dumping doors with the operating mechanism, hereinafter described, in osition. Fig. 2 is a transverse, sectional view, the section being taken on line 2-2 of Fig. 1, and shows the door closed with the latch, hereinafter described, released and the winding shaft in position to support the door, while Fig. 3 shows the winding shaft in its outermost position and held insaid outermost position 'bythe pivoted gravity latch hereinafter re-' ferred to, so as to be out of the path of movement of the door. Figs. 4 and 5 are, respectively elevational and plan views of a bracket hereinafter referred to. V

The figures of the drawings show .only such parts of a dumping car as are neces-' sary to illustrate the invention forming the subject-matter of this application. The remaining portions of the car may be of any preferred type of construction with WlllCll the operating mechanism hereinafter described will operate.

While in the drawings there is illustrated a center sill, a part of the vertical side wall,

cross-bearers and parts of doors which,

when closed, occupy a horizontal position,

as shown .in Fig. 2, it is to be understood that the invention is not limited specifically to that particular type of car, as it shaft with attachments to the several doors so disposed as to automatically release the shaft lock when the doors rise to their closed position.

The invention provides a creeping shaft which, as shown, is located above the floor level of the car, thereby not only increasing the door opening but simplifies the con struction and cheapens the application thereof to the car, means being provided to keep the shaft out of the path of movement of the door during closing movement of the door, while provision is made to prevent lodgment of the load in position to interfere with the positive operation of the door-operating mechanism. Means are also provided to insure movement of the shaft outof the path of the door and its appurtenances when it is desired to dump the load and, when the shaft is moved to its released" osition, said shaft is auto-- matically lock tion (which is the outer-most position, as shown in Fig. 3) until the door rises in its closing movement, when the door-supporting hook or bracket automatically reed and held in locked posileases the pivot gravity latch which enshape, as shown, and is provided with a- This I tion C of the shedding surface of the side'- wall C, by which sheddin incline the operating mechanism hereinafter referred to is protected.

Connected with the side walls C and crossbcarer D are stakes E, which ma be of pressed metal as shown or of any esirable form, which stakes are referably connected with the side wall and the outer ends of the cross-bearers by rivets or electric welding, as may be described.

, Connected with the sills A are brackets F carrying pintles G, on which are secured hinged straps or loops H, which are riveted or otherwise secured to the door and serve as supporting means for the hinge-edge por-- tion of the door in all of its positions.

Connected with the outer or normally free end of the door is a bracket 1, which is adapted to ride over the supporting shaft which bracket is preferably formed of angle smooth horizontal lower face 2. bracket, as shown, is connected by direct rivet connection with the outermost portion of the door and preferably projects beyond the door.

Supported and riding on the, outer end portions of the cross-bearers D are winding shafts 3, which are free to rotate and which are also free to creep or travel transversely, for the purpose hereinafter described.

Connected with the wall portion C at one end and with the stakes E at their opposite ends are a series of shaft-guards 4 which, as shown, are provided with oppositely bent end portions 5 and 6, the portions 5 being inclined to correspond with the inclination of the wall portion C, and the portion 6 extending at right angles to the body portion of the guard to adapt it for engagement with the posts E by direct rivet connection. These guards serve the double function of stiffening the shedding incline of the wall and also to prevent accidenta displacement of the shaft 3.

Connected with the stakes E and suitably supported thereby are short shafts 8, which serve as supports, for gravity latches 9, which latches are adapted to rock on the shafts 8 between the position shown in Figs. 2- and 3. Excessive upward thrust of the latches 9 is prevented by angular-shaped door will be. lifted, "carrying; with it,

stops or plates 12, which are riveted, as shown in Figs. 2- and 3, to the inclined wall portion C, the stops being provided to pre' vent accidental displacement of the-latches beyond their normally operable positions, in which positions the latches may: drop by gravity to engage with the shaft 3.

It will be noted that the lifting chain or cable 18 in lifting the door is Wound on the shaft 3 by movement of the shaft 3 in a clockwise direction, and the unwinding of the shaft in a-contra-clockwise direction will tend to move the shaft outwardly from the.

position shown in Fig. 2 to the position shown. in Fig. 3, thuscarrying the shaft beyond the nose portion 14 of the gravity latch 9 and into a recess 15 formed in said gravity latch, so that the shaft will occupy a; position betweenthe nose 14; and the stop 16 formed on said latch, at 'which time the weight of the latch willautomatically cause the latch to engage the winding shaft "and hold it in its outermost position, sol'that the shaft is out of the path of movement of the door and its appurtenances during closing movement of said door. I

In the claims door in the phrase-out of the path of movement of vthe dooris used in its comprehensive sense of including a door and a doorsupporting hook or bracket, which latter is adapted to lock over the winding shaft to support the door in its closed position. f r j I 'As ,willbe noted in Fig. l, thereare two shaft portions employed which are" inde pendently operable, so that only such bank ofdoors may be 0 erated as Wlll be within the strength of t e person manipulating same, .or within'the power furnishedfor that purpose, and due to the fact that two shafts are thus employed it becomes necessary to 20 is provided, which is formed with a vertical flange-adapted to rest against the'wcb provide a supporti' for the right-hand end portion of the shaft shown at the left-hand side of Fig. 1. To accomplish this a gusset 1:

of the contiguous cross-bearer D and beige cured by suitable rivet connection, as shown, with the stake E, thereby affording a-rigid supportfor the otherwise unsupported ,end of said shaft.

The 0 eration is as-follows door to e in its open "position, as shown in Fig. 3, the gravity latch',9 is in; position'to i embrace the shaft 3,- gb'fith p whemtg -Said. shaft is Wound iii a Clo k i e directi'o ch in its outermost position, but when the door' the is lifted high enough the bracket 1 will engage the under faceoflthenose l4 of the latch, thereby lifting'the latch on its pivot, as shown 1n Fig. 2, whereupon continued rotation .of the shaft will cause the shaft to leave its outermost position, shown in Fig. 3, and be drawn to the position shown in Fig. 2, in. which latter position the shaft rests under the face 2 of the bracket 1, and the load incident to the weight of the door and contents of the car is transferred from the winding chain 13 to the supporting bracket 1, and t'husto the winding shaft, which now serves as a support for the doors, the bracket 1 resting on the shaft until a contra-clockwise movement of the shaft will retract it from its position under said bracket, whereupon the weight of the load will automatically cause the door to drop and dump the load.

When the door is closedit will be noted that the roughened collar 22 rests upon the roughened bracket 21, which is secured to one of the diaphragms D. The bracket 21 is shown in dotted lines in Figs. 2 and 3 and is shown in plan in Fig. 1 secured to the left-hand diaphragm under thecollar 22. The collar 22 being ofgreater diameter than the-shaft 3, it is evident that the weight of the load will force the collar downwardly into engagement with the top surface of the bracket, so as to insure positive engagement therewith in the opening movement of the door, thereby insuring positive release of the shaft 3 from under the door-supporting,

brackets 1. But one bracket 21 and collar 22 are shown, but it is evident that as many of each as may be required will be used.
